Made of felted wool, often pointy and erring on the unflattering, the latest thing everyone’s wearing hasn’t come from the catwalk or celebrities, but rather from the wintery wilds of Scandinavia.

As standalone saunas continue to surge in popularity (the British Sauna Society says there are now 147 publicly bookable high-quality authentic saunas in the UK), special sauna hats are becoming a British social media phenomenon, selling out online and popping up on hot heads up and down the country. They’re artfully arranged in interiors photo shoots too, an indicator of the owner’s healthy-living lifestyle, and that they know their hot box from their cold plunge. Some have even hailed them as 2025’s answer to the Dryrobe.
